It is well known that when by accident there is only partial entry of shuttles into their boxes in looms having a plurality of shuttles, accidents occur which often prove serious.

According to the invention each shuttle under normal conditions automatically penetrates by simple means into the interior of the corresponding box. The means employed consists essentially of a thrusting member for the shuttles, which has an angular shape and is adapted to rock on a pivot pin mounted on the loom frame, which thrusting member is subject to the action of a spring which tends to maintain the trusting member in a determined position, in such manner that in the downward movement of the boxes as a whole, if a shuttle be left in a slightly abnormal position by not com pletely entering into the box, that shuttle encounters the thrusting member which moves upon its pivot pin in overcoming the action of the spring, the spring then causing the thrusting member to rock in an opposite direction, forcing the shuttle towards its box until it comes into the normal position.

The invention comprises the constructional features hereinafter described with reference to the accompanying drawing.

Figure 1 is a view in vertical projection of the corresponding parts, when the machine is working normally.

Figure 2 is a view showing what happens if a shuttle does not completely re-enter its box.

Figure 3 represents in horizontal projection a detail hereinafter described.

The frame 1 of the loom has pivoted at 2 the thrusting member 3 having an angular form and on one of whose sides a rod 4 is supported, subjected to the action of a compression spring 5 through which it passes, and placed within a support 6, the said spring ensuring that the upper part or side of the angle 3 always remains very nearly in a horizontal position.

Boxes 7 8, 9, 1O correspond to the shuttles 11, 12, 13, 14 and form an integral casing which as it is known has an up and down movement. If the shuttles enter quite normally ure 1, said b into their boxesyas indicatedfin Figthe device remains inactive, while the oxes descend as awhole; 'If a shuttle,

for example, the shuttle 13 rests abnormally a little outside its box 9, then on the descent of the boxes the shuttle 13 strikes against the thrusting member which is madeto rock backwards on its pivot pin 2 in'overcoming the action of the spring 5; but this spring by its reaction tends to make the thrusting member 3 rise, which, by sliding against the point back,

into the box 9. I
